2 Claims.

This invention relates to a jiffy milk cooler.

An object of the invention is the construction of a novel and efficient milk cooler of special value to a small dairyman, by reason of its simplicity and low cost of manufacture.

Another object of the invention is the construction of an ecient apparatus that can be easily placed upon a milk can, and retained in position thereon during the operation.

With the foregoing and other objects in view, the invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a view partly in elevation and partly in vertical section of an apparatus constructed in accordance with the present invention, while Figure 2 is a top plan view.

Figure 3 is a sectional view taken on line 33, Figure 1, and looking in the direction of the arrows.

Referring to the drawing, in which the preferred embodiment of this apparatus is illustrated, I designates an ordinary milk can, and 2 is a support upon which are mounted the vertical units 3; these vertical units are in the nature of rods or shafts, or the like.

Mounted upon the can I is a head 4 which is provided with a removable cover 5. The head 4 is provided with an annular bevel which produces a narrow lower end 1 upon the head 4. A gasket 8 is placed upon the annular bevel 6 and presses upon the mouth of can I. This produces a tight connection, as the weight of the head and its associated parts cause the gasket to be substantially jammed against the lower endV of the bevel 6, holding the gasket eii'iciently in place and producing an excellent result.

A rack 9 is employed, comprising two arms I and an integral semi-circular band II. Band I I is xedly secured to head 4. The arms I0 bear against the inner portions of the vertical units 3, Fig. 2. Clamps I2 are partly around the vertical units 3 and are fastened by any suitable means I3 upon the arms I0. By releasing the fastening means I3, the rack 9 can be moved vertically upon the vertical units 3.

A suitable funnel I4 is supported upon the head cover 5, whereby the milk can be deposited in the can I.

Mounted upon the head cover is an agitator shaft bearing I5. A rotatable sleeve I 6 is within bearing I5. A drive pulley I1 is xedly secured to the sleeve I6, against the upper end of bearing I5. A vertical shaft I8 is ilxedly secured within sleeve IB and rotates simultaneously with the sleeve I6 and pulley I1. On shaft I3 and just under the head cover 5 is a sediment cup I9. Fastened to the lower end of the shaft I8 are agitator blades 20.

Cooling coils 2I are placed around shaft I8, and one end 22 communicates with a suitable source of supply of brine when brine is used in the apparatus. The other end 23 communicates with the pump 24, the pump 24 being used when brine is employed in the apparatus, although the pump can be replaced by an expansion valve when refrigeration gas is used.

'I'he pump 24 is in communication, through shaft 25 with the motor 26; in other words, through shaft 25 the pump 24 is operated. The shaft 25 of the motor extends beyond the upper end of said motor, and carries a small pulley Ila; on pulleys I1 and I'Ia is a belt 21, whereby the motor 26 rotates the agitator blades 20. On the extreme upper end of shaft 25 is a fan 28; fan 28 is positioned in the vacuum fan casing 29. Casing 29 is supported upon the bracket 30, which bracket has its lower ends fastened to arms I 0 of the rack 9, per Figure 2. A tube 3l communicates at one end with the interior of vacuum fan casing 29 and its other end with the interior of the head 6, whereby when the motoris operating, the fumes, etc. in the can I can be drawn therefrom and discharged to the outer atmosphere through the opening 32.

A temperature control 33 is employed, supported by one of the vertical units 3. If refrigerant brine is used in the coils 2|, instead of regular refrigerant the apparatus will work just as efficient, owing to its construction.

It will be understood that when the motor 26 is operating that the fan 28, pump 2l and the agitator, constituted by agitator blades 20 will all operate simultaneously, producing an eicient cooling of the milk in can I. The apparatus is comparatively simple in construction, and requires a relatively small space for placement, whereby it is particularly attractive to a dairyman operating on a simple or somewhat restricted basis.

While I have described the preferred embodiments of my invention and illustrated same in the accompanying drawing, certain changes or alterations may appear to one skilled in the art to which this invention relates during lthe extensive manufacture of same, and I. therefore,

reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is: y

1. In an apparatus of the class described, the combination with a support, of vertical units on said support, an adjustable rack on said vertical unitsi a head carried by said rack, a motor carried by said rack, a suction fan supported upon said rack. means connecting said suction fan to said head, an agitator carried by said head, cooling means mounted upon said head, a pump in communication with said cooling means, and means connecting said motor to said agitator, fan and pump, whereby said units are simultaneously operated.
